The number of users who get access to wireless links is increasing each day and many new applications require very high data rates. The increasing demand for higher data rates has led to the development of new techniques to increase spectrum efficiency to achieve this goal. However, the limited bandwidth of the frequency bands that are currently used for wireless communication bounds the maximum data rate possible.

In the past few years, researchers have developed new devices that work as Terahertz (THz) transmitters and receivers. The development of these devices and the large available bandwidth of the THz band is a possible solution to this ever increasing demand.

However, THz communication is still in its infancy and more research needs to be done to bring THz technology into every day life.

In this research, we study wireless THz communication systems. As the first step, we conducted detailed channel measurements to study and analyze the characteristics of THz signals under different channel conditions. These propagation models mimic the behavior of THz signals in real applications. Then we use these models to study appropriate modulation methods for directional and omni-directional THz channels. We also use pulsed THz signals in wireless communication channels to send data at a very high rate. We have developed rate adaptation algorithms to allow multiple users to share the same THz channel for downlink applications while fairness is maintained among them.
